In the broad sense of the term “corporate information systems” – CIS is considered as a common set of functional as well as providing subsystems typical for economic information systems (hereinafter simply EIS). In a more narrow sense, corporate systems are called software, the implementation of which allows for the comprehensive automation of enterprise activities (for example, Galaxy, AVACCO, R/3).
One of the main properties of EIS is the divisibility into subsystems, which has a number of advantages in terms of the development and operation of EIS, which include:
1. Simplification of the development and modernization of EIS as a result of the specialization of design teams by subsystems.
2. Simplification of the introduction and delivery of ready subsystems in accordance with the order of execution of work.
3. Simplify the operation of EIS due to the specialization of employees in the domain.
In the practice of enterprise automation, the concept of EIS is used in two aspects: in the first aspect, EIS is considered as a software complex designed to solve various economic and management problems; in the second aspect, EIS is considered more widely. At the same time, as part of the EIS, many subsystems are distinguished, which are divided into two large groups: functional subsystems and providing subsystems.
Functional subsystems of EIS are used to service certain types of enterprise activities. The subsystems providing information, technical, mathematical, software, organizational, legal, and also linguistic support belong to the group of providing subsystems.
